When to Call the Doctor

Heat stroke is a medical emergency; any signs or symptoms of this condition
should prompt a call to emergency services (911). Meanwhile, immediately begin
first aid by cooling the person – move them to shade or an air conditioned
building, remove constricting or clothing layers, and cool the person with
evaporative cooling (mist or spray water on the patient while fans are running).
Some experts recommend placing ice packs or wet towels to the head, neck,
armpits, and groin.
